Uh actually he does a lot of tamer. Ofcourse it has to be based on academic so there is more important topics. And plus the title of genius tamer, it has already said in some of the chapters where he is genius for taking all of the reptiles while no one can do that much.
You said that his genius when it comes to reptiles but the story doesnt really give me that most of the time he has 1 red dragon and then got the white one but rarely make an appearance
And then suddenly apparently he could tame the cube but only for stiry that he could do it and not really explore how to use the cube itself just for that all got stolen by the main villain who is so strong the mc need to be trap in a time stop place for him could defeat him in one shot lol
All i want is if you going to make a comic and the tittle is genius tamer exolore on that thing i dont really need him be op or whatever i just want him to do deep dive in that taming shit and have that as his main skill
For a manhwa that have a title "genius tamer" He rarely do taming stuff and of course close to the end he become op but still rarely do the taming skill lol
